The WRA_CKS-1W & WRB_CKS-1W Series
are specially designed for applications where a
wide range input voltage power supplies are
isolated from the input power supply in a
distributed power supply system on a circuit
board.
These products apply to:
1) Where the voltage of the input power supply
is wide range (voltage range≤ 2:1);
2) Where isolation is necessary between input
and output(isolation voltage≤1500VDC);
3) Where the regulation of the output voltage
and the output ripple noise are demanded.
